WRAPPER CUTTING AND TRANSFERRING MECHANISM.

Specification of Letters Patent.

Patented July 30, 1907.

Application filed January 17,1903. Serial No. 139,370.

To all whom it may concern:

Be it known that I, OSCAR HAMMnRs'rEIN, a citizen of theUnited States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented certain new and useful Improvements in Wrapper Cutting and Transferring Machines, of which the following is a specification.

My invention relates to wrapper cutting and transferring machines and has for its particular object to produce a machine in which the wrappers may be quickly and economically cut and properly trans ported to a storage apparatus.

, In the accompanying drawing I have illustrated a machine showing the principles of my invention, it being understood that I do not thereby limit myself to the machine therein shown as the invention will find its embodiment in a variety of constructions.

In the drawing, Figure I is a plan view of the machine; Fig. II is a sectional elevation on line IIII of Fig. I; Fig. III is an enlarged underneath view of the suction box and its operating means; and Fig. IV is a section on line IVIV of Fig. III.

In the drawing, 8 represents the frame of the machine which may be of any desired or preferred construction. Mounted in suitable brackets on the frame of the machine is a suction pipe or chamber 9 capable of being rotated and provided with a pinion 10 and sector 11 or other suitable means for rotating or otherwise moving the same. The sector 11 may receive motion from an arm 12 which may be suitably actuated. The suction pipe 9 connects by a trunk 14 with a suction box a shown as provided with a perforated top I) having a cutting corner or edge f.

Lying against the face of the top of the suction box is a follower 15 mounted on rods or plungers 16; or otherwise suitably mounted, which rods or plungers are provided with springs 17, normally holding the follower in position, preferably against the face of the top of the suction box. In practice this follower is made of thinner material than it is convenient to show in the drawing and preferably has perforations opposite those in the top of the suction box b. The suction box may be adjusted to normally rest upon a table 1) and has associated therewith a yoke or frame 18 pivoted to the suction pipe and bearing against the plungers 16 and provided with one or more plates or other suitable engaging devices 19 which are adapted to en gage. and be frictionally held by suitable latches 20 preferably mounted on the table 1) and whose operation will be given in detail subsequently. A pin 19 on the suction box serves to effect the movement of the yoke or frame 19 in one direction.

In order to arrange for the storage of wrappers, I provide a suitable storage box or compartment 21 having therein a block or receptacle 22 held in such manner as to be allowed to gradually descend as wrappers are piled in the box. v

' In order to effect the cutting of the wrappers, I preferably provide an arm m provided with pivots h upon which are freely journaled brackets j carrying freely rotatable travelers (Z and 0 herein shown as balls. These travelers are arranged to traverse the peripheral edge or corner f to effect the cutting, each traveler running around the extent of one half of the said edge on each traverse or movement of the arm on which carries said travelers, the travelers being made to exert a latcral pressure on the edgcf, by the springs 1" attached at one end to each bracket 9' and at the other end to the arm m.

The specific cutting apparatus indicated in the drawings forms the subject-matter of another application filed by me in the United States Patent Oflice on January 18, 1902, Serial No. 90,327, and renewed on September 5, 1902, Serial No. 122,206, in which application such cutting apparatus is more fully disclosed.

The operation is as follows: A tobacco leaf is spread under tension of the air suction (of the suction pipe 9) on the top flat surface of the follower 15 and face of suction-box b, the arm m is given a sweep (in the present instance by hand) so as to run its travelers completely around the cdgef by which means the wrapper is cut. The arm m having ngw been moved out of the way, a movement is given to the lever 12 in any suitable manner as by the foot of the operator by which through the medium of the sector 11 and gear 10 the portion of the suction pipe or chamber 9 which carries the suction box a, and on which the frame 18 is pivoted or mounted is swung on its axis so as to swing the suction box and frame to bring the said suction box into position at the entrance of the wrapper receptacle 21 where the wrapper on the suction box is brought into contact with the movable block or support 22 or, if other operations such as is now being described have already taken place, upon the pile of wrappers previously deposited on the said block or support. The pin 19* serves to effect this movement of the frame 18 and to bring the frame 18 into position to engage the spring latches 20.

When the swinging movement of the suction box has been completed it will be found that the catches or springs 19 have become engaged with the spring latches 20 and are frictionally held thereby so as to allow a slight lost motion of the frame 18 upon its return rotation which is effected by a reverse movement of the lever 12, whereby the plungers 16 are held stationary during the beginning of the return movement of the suction box a to its initial position shown in Figs. I and II. In this manner the follower 15 will remain behind during the beginning of the return movement of the suction box and will separate the wrapper from the suction box thus relieving it of the tension of the air suction and whatever adhesion may eXist by reason of stickiness and hold it firmly to the pile of wrappers in the receptacle 21. As the suction box continues to move, it will swing the yoke or frame 18 releasing it from its frictional engagement with the spring latch 20 thereby permitting the springs 17 to move the plungers 16 to bring the follower firmly against the face Z) of the suction box a. These wrappers thus piled will remain .stretched fora time and may be used for wrapping cigars. The block 22- is arranged either by frictional devices or 0th crwise so as to recede into the receptacle as the pile of wrappers becomes thicker and when the pile contains the desired number of wrappers the wrappers may be removed from the receptacle and stored for future use or used at once, as desired.

Having described my invention, what I claim and desire to secure by Letters Patent is 1. The combination of means for supporting a wrapper in position to be cut, means c'oiiperating with the said first mentioned means for effecting the cutting of the wrapper on the same, means for moving the wrapper sup port into another position when it is desired to deliver a wrapper and a device for mechanically engaging the wrapper and remoy'ing it from the face of the wrapper support.
